(Warning! Stuff in this chapter might be a little triggering, like talking about gore, spirits, death, curses, and human-eating supernatural creatures. The scenarios are based off the music and stuff in the video above. Feel free to tweak scenarios or make up your own. Swapping the characters is fine.The entire theme of this chapter is supernatural stuff, and twisted love, so yeah. This roleplay can pretty much go any way, but it's likely to be fairly dark despite if it's fluff, angst, or something else following the plot.)

Scenario 1: 
(Oc) was a spirit, trapped in an old house out in the middle of nowhere. While everything in their house was preserved to time, no one ever came across them. It had been so long since they had been seen another human, and to be totally honest, their mental state had started to crumble.
So of course, when (Crush) somehow stumbled across their house during a storm, and decided to stay inside in the living room..they were quite happy.  Locking the doors to the outside, they crept up on (Crush), taking their hand and hugging them, snickering to themself as the other attempted to pull away fearfully.

Scenario 2:
(Oc) was a malevolent spirit who had been cursed to forever stay in their home, hidden away in the woods. They fed off human energy, slowly absorbing their life force. However, it had been quite a long time since they had fed, so when (Crush) showed up to explore their house, they were delighted. After all, perhaps this would be just what they needed to make life interesting again.
Trapping (Crush) in a room, they approached, telling them what would happen. However, panicking, (Crush) offered to go out and find a way to break their curse. To make sure they kept their word, (Oc) forced them to swear on their soul, and decided to accompany them by sending their voice through a necklace placed around (Crush)'s throat, and showing up in their dreams.

Scenario 3:
(Oc) was a ghost, or a demon. They didn't really remember at this point, to be honest. All they knew was that they had to eat people to survive. They mostly stayed in their old home, which they kept up. They didn't leave too often, or eat. They knew they could pretty much eat any human, though usually when they came across someone in the woods, they would only take a quick bite of their arm, or drink some of their blood, absorbing a small bit of their soul. However, most times they could get by with eating farm animals or woodland creatures. So when (Crush) made their way into their home, trespassing, they were angry. But, the main reason for what they did was loneliness, and boredom. So, they kept the other trapped in their house, unable to escape, occasionally feeding on them by drinking small amounts of their blood. They didn't exactly plan to break the other's spirit, but...well, (Crush) slowly gave up on leaving. Which was good, because it meant (Oc) could leave windows open for them and stuff without worrying about them escaping! So, this wasn't that bad, right? Except (Crush), their little pet human, seemed a lot more lethargic and sad lately...

Scenario 4:
(Oc) was a demon, who had been cursed a long time ago to stay in their mansion, which kept itself clean. It appeared in the human world ever so often, luring in adventurers who would become trapped there for the rest of their life. Sometimes, they would be eaten, sometimes tormented, sometimes kept as human pets. All for the enjoyment and amusement of (Oc), who was quite powerful. After (Crush) fell into their world, though, they found themself interested in the human, deciding to keep them around. Bringing them food, and giving them their own room. And after a while, they had forced the other to start talking to them, explaining why they kept them around. After all, it was interesting to toy around with them, and after a while (Crush) seemed to give up on hating them...

Scenario 5:
(Oc) was a demon, who had been cursed a long time ago to only stay in their mansion, which kept itself clean and appeared in the human world occasionally, luring in people who would become trapped there for the rest of their life. Sometimes, they would be eaten, sometimes sometimes killed immidiantly, sometimes kept around for a while then killed. Originally, when (Crush) fell into (Oc)'s trap, they intended to eat the other, as they were hungry, and the magical human food didn't quite cut it. It was just bland. But, after (Crush) seemed slightly entertaining, they decided to keep them for a while. So, they kept the other with them, actually becoming quite attached to the human. It wasn't like (Crush) would risk being killed, so they usually just went along with (Oc), whether it was dancing, spending time together, talking, or being pulled into a kiss. After all, why make such a powerful creature angry? (Oc) had offered to make them immortal and keep them around forever, so (Crush) had no idea what they could really do. Was it love? That was..debatable. If it was, it was a twisted, manipulating, ugly thing. Really, it was just more like (Crush) had given up on resisting or fighting back whatsoever. More like Stockholm syndrome than anything else.

Scenario 6 PT1:
(Note, either way whoever's the demon will be a little taller than the human. They can change their height to their ingame height or something later on, but they're probably going to be around 2-5 inches taller then the human character.)
There's a reason people didn't usually hunt demons.
It was a dangerous job, that had almost gotten (Crush) killed, many, many times.
After all, these creatures were powerful. 
(Crush) had been warned about going into the woods at a certain time. A giant house would appear, where supposedly one of the most powerful demons would reside..
And they had gone to the center of the forest, armed, and waited until the house appeared in the clearing.
Creeping in, they found the door had locked behind them. The house was much bigger on the inside, lavished decorations. 
They looked around, exploring. Sneaking up the stairs, prepared to attack. However, upon looking into the rooms, and attics, all they found were some photos and items that they didn't know were significant to (Oc), the demon.
As the clock struck midnight, they crept back down the stairs, this time into the main hall. The colors were dark, matching (Oc)'s aesthetic. And as the grandfather clock chimed, they saw (Oc) standing there in a formal outfit, in the middle of the hall.
(Crush) found themself dropping their weapons, stepping off the bottom step as (Oc) approached them. They were entranced, and even though part of them warned them to leave, leave now, they found themself sunken deep, deep into that trancelike state, approaching the other who moved towards them as well.
(Oc) took their hand- they had long, painted nails- , lifting one of (Crush)'s arms up, pulling the other to rest by their waist.
And with that, (Oc) began to lead (Crush) in a dance, keeping the other close to them. 
It felt like it took hours, (Crush) almost felt tired, but it was odd, as if they weren't in their body. They felt the creeping hints of exhaustion, yet they didn't stumble, their muscles didn't burn. Some hint of coherence stirred within them, an old thought. Not to let a demon trick you into falling in love with them, because then the demon could turn you into a lesser demon, and could control you to a degree. Or was it you would be bound to them forever? Something along those lines.
Some demons could trick a human into falling in love with them through flowers, through a kiss, some attempted to mirror human courtship rituals.
However, that didn't seem quite important to (Crush) as they found themselves pressed up against (Oc) for a few steps, before being twirled back into the dance.
It seemed like they were dancing forever, but finally (Oc) tugged the other close to them once again, pressing a hand to the back of (Crush)'s hair to tilt their head up to make eye contact with the other. At some point during the dance, (Oc) had slipped a flower/elaborate pin/decoration in (Crush)'s hair. Some bit of their original thoughts began to return to (Crush), as they found themself becoming unsteady on their feet as the spell started to wear off. And then, (Oc) leaned in for a kiss.
(Note, you can stop and roleplay from here, or continue further down the scenario's plot.)

Scenario 6 PT2:
(Crush) couldn't find it in them to resist, and they found (Oc)'s lips pressed against their's, their eyes wide.
After a moment, under (Oc)'s cool gaze, they flushed ever so slightly, eyes fluttering shut as they sunk into the other. Had the demon bitten their lip? Maybe?
Watching them, (Oc) closed their eyes as well before pulling away, running their fingers through (Crush)'s hair. Stepping back, they tilted their head, a small, cold smile on their lips. And with that, they gestured, beckoning the other to follow them.
Obediently following the other, fearful, (Crush) was lead up the stairs and had the door opened for them, where they were shown into a room. Making their way to the bed and sitting down, they placed their head in their hands, trying to make some bit of sense from what was going on. Despite this, the imminent danger they were in didn't occur to them for a moment as they puzzled over the dance, the kiss, the whole string of events.
(Note. You can start roleplaying  with the plot from part one to here, or continue on.)

Scenario 6 PT3:
As they sat there, (Oc) approached (Crush), letting the door swing closed. (Crush) looked up at them with some alarm as (Oc) sat besides them, taking their hand and tracing their nails down (Crush)'s wrist with some sort of that tiny smirk from before.
(Crush) wasn't sure if they were scared, embarrassed, or angry. Maybe some sort of combination of all those things.
To their surprise, (Oc) placed their chin atop (Crush)'s head, giving a soft sigh and wrapping their arms around the other's waist.
With that, they mumbled something into the (Crush)'s hair, the first sound they had made that wasn't a sort of chuckle.
Rather timidly, (Crush) spoke up, asking what they had said.
Clearing their throat, (Oc) spoke for the first time that night, their voice strangely almost hypnotic. Something about their tone was enchanting.
"Ah...it's so nice to have company again~"
They finished the statement with a chilling sort of laugh.
(Note. You can stop and roleplay from part one to here now, or continue to the last part of this scenario.)

Scenario 6 PT4:
Smiling, (Oc) wrapped their arms fully around the other, laying down. (Crush) allowed this to happen, flinching slightly, and found themself tugged up against the demon, who was kind of..hugging them.
However, after a while of fear and staying still, (Crush) finally passed out, sleeping soundly for the rest of the night and only awakening late into the morning, finding themselves wrapped up, entangled with the sleeping demon, who was kind of...cuddling them? Somehow, they didn't feel as scared as before, despite what their instincts warned.
